Symptom

Numlock wird nicht über die Registry mit "InitialKeyboardIndicators" = 2 gesetzt

Cause

Die Registry ist nicht immer die Lösung

Solution

Ich habe eine kleine Anwendung in C geschrieben, die die NUMLock Taste checkt und setzen kann. Du kannst es in einem C Compiler erzeugen oder ggf. im Downloadbereicht von Lubby herunterladen.

Im folgenden Beispiel wird das Programm in ein Anmeldeskript mit Hilfe von VBScript eingebunden:
    Set oShell = WScript.CreateObject ("WSCript.shell")
    oShell.run "cmd /C CD C:\ & %logonserver%\netlogon\NUMLOCK-on.exe"

----------------------------
C Quellcode:

// NUMLOCK-on.cpp : Programmed by Wim Peeters.
//

#include "stdafx.h"


int _tmain(int argc, _TCHAR* argv[])
{
    SHORT myshort;
    int thekey; //#define VK_NUMLOCK        0x90 can be found in winuser.h (Wim)

    thekey=144; //this should be 0x90 VK_NUMLOCK

    myshort = GetKeyState(thekey);
    printf("Programmed by Wim Peeters\n");
    //printf("your NUMLOCK key is %d\n",myshort);
    if(myshort==1)
    {
        printf("NUMLOCK is already on\n");
    }
    else
    {
        printf("NUMLOCK is off, switching it to on\n");       
        keybd_event(thekey,1,0,0);
        keybd_event(thekey,1,KEYEVENTF_KEYUP,0);
    }

    return 0;
}
